IMPROVEMENT IN ASH-LEACHES.

Specification forming part of Letters Patent No. 1 50,214, dated April28, 1874; application filed March 14, 1874.

To all whom it may concern:

Be it known that I,Jo111v WOOLRIDGE, of Deans Corners, Lake county,Illinois, have invented a new and useful Improvement in Leach-Tubs, ofwhich the following is a full description, reference being had to theaccompanying drawings.

Figure 1 is an elevation; Figs. 2 and 3, details.

My invention consists in providing a leachtub with a receiver, into'which the lye from the ashes will pass and be conveyed to a singlepoint, from which it will flow into a suitable receptacle, and insuspending such tub sov that it can be emptied by tipping, as described.

' In the drawings, A represents a leach-tub,

which, for convenience, is quite small at the bottom. B B are suitableposts, to the upper ends of which the tub is pivoted by means oftrunnions a. G is a latch, by means of which the tub can be locked inthe position shown in Fig. 1 while in use, the lower end of the latchengaging in anotch in b. The tub has a perforated bottom. D is areceiver, concave on the inside, and of such size as to catch all thatflows from the tub. At the center, as shown, it is provided wit-h asmall tube, .0, through which all the lye can pass to a suitablereceptacle. If the hole for the escape of the lye from the receiver D beplaced in the center, the tube c'need not be used, though it will beadvisable to use it to prevent the lye from spreading over the underside of D. The receiver D might be provided with a lip at one side topermit and direct the outflow of the lye. As represented, this receiverD is secured to the tub by means of two hasps, d, and staples 0, one oneach side of same. f is a hook to prevent the hasp from slipping offfrom the staple. A hook or pin is used with each hasp and staple. One orboth the hasps may be hinged to D.

I do not confine myself to this specific mode of securing the receiver Din place. Y

The tub can most conveniently be made of staves and circular in form. I

The receiver D can best be stamped up from sheet metal, and beingremovable, when the tub is not in use, it (the receiver D) can be putaway in a dry place for preservation.

' The tub being suspended on trunnions, it can be tipped over withoutbeing removed fromthe posts, for the purpose of removing the contentswhen desired.

By the use of this improved leach-tub, waste of lye can be easilyprevented, the contents can be emptied with little labor, andconsiderable annoyance attending the common meth ods will be avoided.

What I claim as new is as follows:

1. The tub A, in combination with the receiver D, substantially as andfor the purposes specified.

2. The combination of the tub A,-receiver D, trunnions a, and lock b,substantially as and for the purposes specified.

JOHN, WOOLRIDGE.
